CONSTRUCTING OR FORMING CAR-TRUCKS.

SPECIFICATION forming part of Letters Patent No. 737,810, dated September 1, 1903.

Application filed July 20, 1896. Serial No. 599,835. (No model.)

To a/ZZ whom, it may concern:

Be it known that we, RANSOM C. -WRIGHT, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, and FRANK E. STEBBINS, residing at l/Vashington city, District of Columbia, citizens of the United States, have invented certain new and useful Improvements in Constructing or Forming Car-Trucks; and we do declare the following to be a full, clear, and exact description of the invention, suoli as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

The objects of our invention are, first, to form a truck of great strength and principally of merchantable rolled forms whereby great strains may be resisted; secondly, to unite the rolled forms to the pedestals which control the wheels, axles, and boxes in a. manner easily accomplished in any ordinary shop and without the use of special tools and machinery over and above the ordinary appliances; thirdly,to so form and shape the pedestals that they shall have ample strength to perform their work and so they can readily be made in any foundry adapted to make the usual run of railwaycastings, and, finally, the provision of pedestals having webs or extensions at right angles to the jaws, which can be easily secured to the webs at the ends of the rolled or flanged side frames and likewise easily removed and other pedestals applied.

Our invention consists in certain novelties of construction and combinations of parts hereinafter set forth and claimed.

We have disclosed our best methods and forms of constructions and combinations in connection with the accompanying drawings.

Figure 1 is a side elevation of a truck-frame having channel sides and transoms and cast pedestals. Fig. 2 is a half-plan of Fig. 1. Fig. 3 is averticalsection on line a a,Fig. 2. Fig.4is a plan of apedestal united to a channel-beam, and Fig. 5 is an elevation view of Fig. 4. Fig. 6 is a plan of a pedestal united to two channelbeams placed with their webs in contact and forming an I-shaped beam. elevation` view of Fig. G, and Fig. S is a sec- Fig. 7 is a side tion on line :n of Fig. 7. Fig. 9 is a plan of a pedestal united to an I-beam. Fig. 10 is an elevation of Fig. 9, and Fig. 11 is a sectionon line fu fu of Fig. 10. Fig. 12 is a plan of a pedestal also united to an I-beam, and Fig. 13 is an elevation of the same.

In Figs. 1, 2, and 3 the side channel-beam 1 has its flanges 2 3 turned in or toward the center of the truck, leaving a smooth outer side upon which pedestals 4 5 are secured by means of'webs or extensions 6, which seat on the outer face of the channel-bar 1 and are secured thereto by rivets 7, while an upper flange S and a lower flange 9 project inwardly over lianges 2 3 and, fitting snugly, take the shearing strain off of the rivets. The pedestals have jaws 10, formed with wearing-iianges 11, against which the axle-boxes bear, the jaws being united at the top by spring-pockets 12 and held at the bottom by ties 13 and secured by bolts 14 15, a tie being removable whenever an axle-box is required to be placed or displaced between jaws 10. A web 16 joins iiange 8, extends over pocket 12 and down the outer flange 11 for added strength, while a flange 17 joins lower flange 9 and inner flange 11 for the same purpose. Transoms 18 19, of channel shape, extend across the truck from side to side, with the iianges extending outwardly and are united to each side channel 1,

as follows: A support 20, of cast material,v

preferably malleable iron or cast-steel, has a part 21, which lits inside of channel 1, extending each way from the center, and is secured by rivets 23. A part 23 lits under flange 2 and a part 24 iits inside of flange 3 and ex tends inwardly, and thereon rest transoms 18 19, secured by rivets 25 through their lower flanges 26. From part 24 are raised lianges 27 28, against which the inneror flat sides of channels 18 19 fit and where they are secured by rivets 29.

In Figs. 4 and 5 is shown a form of pedestal adapted to be attached to a channel-beam 46. This pedestal has a jaw formed by a long wall 4S and a short outer wall 49, joined at the top by double spring-pockets 50 51, and at the bottom and outer side of the jaws the opening is closed by an angular shaped tie 53, secured by bolts 54 55, and upon the vertical part of the tie is awall 56, as a continu ICO ation of wall 49. A flange 57 projects from wall 49 outwardly and passes over springpockets 50 5l for stiffness, and there is a central partition 58 between the spring-seats for the same purpose. The channel-bar 46 has flanges 59 60, and its web is united to web or extension 61 by rivets 62, while flanges 63 above and 64 below the channel form a pocket for the channel end and take the shearing strains off of rivets 62. Web 65 unites flange 64 and web 48.

In Figs. 6, 7, and 8 is shown a pedestal having jaws 30, formed by walls 31 32, joined by a spring-pocket 33 for a single coil-spring at the top and held by a tie 34 at the bottom, secured by bolts 35 36. A web 37 adjoins spring-pocket 33. This pedestal is adapted to be secured to two channel-beams 38 38, placed between webs or extension 39 40, projecting outwardly from wall 32 and at right angles to the jaws and between which the two channel-beams rest, the webs of the beams being secured by rivets 45 through extensions 39 40.

In Figs. 9, l0, and 11 is shown a form of pedestal adapted to be attached to an I-beam and have double springs. The jaws 65 are formed by walls 66 67 and spring-pockets 68 69 and united at their lower ends by tie 70, secured by bolts 71 72. A partition or web 73 unites walls 66 67 at the top and separates the spring-pockets. The I-beam 76 is inserted intoa seat formed between webs or extensions 77 78, reaching out from wall 67. Rivets 83 pass through the web of the I-beam and webs or extensions 77 7 8. A flange 84 unites wall 66 and the spring-seat tops and adds stiffness, while flange 85 unites wall 67 and extensions 77 78.

In Figs. 12, 13 is shown still another form of pedestal, also attached to an I-beam. The jaw 86 is formed with a back wall 87, which also extends outward and forms the bottom piece 88, and a removable piece 89 forms the outer jaw. The jaw locks onto part 88 by side flanges 90 and has a bolt 91 extending perpendicularly through it and through pedestal head 92. This pedestal has double spring-pockets 93 94, and from wall `87 are double webs or extensions 96 97, between which web 98 of the I -beam is secured by rivets 99. The web may extend to the wall 87 3 but its flanges 100 101 are cut short and abutv head 92 and bottom stiffening flange 102, making a very firm support and relieving the rivets from shear.

It will be observed that in all the examples the main parts of the frames consist of flanged beams, that the ends of the, sides are plain and free prior to the application of the pedestals, and that the said cast-metal pedestals are integral, aside from the tie-pieces, and secured to the ends of the side frames orflanged beams by their integralwebs or extensions, which are at right angles to the jaws, being placed in frictional contact with the webs of the flanged beams and riveted in position.

In Figs. 1, 2, and 3 we have illustrated channelbeam transoms which unite two side frames consisting of rolled channel-beams. The same type of transom-beams may be used to unite the sides of the channel, double channel, or I-beam side frames shown in the remaining examples. However, other types of transom may be employed to unite the side frames, inasmuch as the chief novelty dise closed in these examples resides in the side frames and pedestals and the methods of their union. In all cases except Figs. 12,13 the ends of the flanged side frames are shown cut off square; but they may be cut off at an angle or part of the webs or flanges removed at the ends and the cast-metal pedestals slightly altered in shape, so as to admit of facile attachment through the medium of their webs or extensions, and such slight changesV we shall not consider as substantial departures from our invention. The seats or pockets for springs may be made independently of the integralcast pedestals, if desired, without destroying the integral character of the pedestal.

In Figs. 1, 2, and 3 a side frame and portions of the transoms only are illustrated. The complemental portions of the complete truck-frame are essentially duplications and for that reason not reproduced. The remaining figures show one end of each of the other four examples of side frames with pedestals attached. The opposite ends of the frames are in each case mere duplicates, and hence omitted.

It yshould be understood that any one of the four side frames can be substituted for the side frame shown in Figs. 1, 2, 3 and the parts duplicated to constitute an entire and complete truck-frame.
